Consider conducting a hypothesis test in which the null and alternative hypotheses are:
Ho: ? ? c
Ha: ? > c
Where c is some hypothesized value.
Suppose the significance level is 0.02, the test statistic is
positive, and the statistical decision is to FTR Ho.
If we redo the test at ? = 0.05, our statistical decision
would be: ---Select--- There is not enough information
to make a decision at 0.05 FTR Ho at ? = 0.05 Reject Ho at ? =
0.05
A. There is not enough information to make a decision at 0.05
B. FTR Ho at a= 0.05
C. Reject Ho at a= 0.05
here as we fail to rjeect Ho at 0.02 level whcih means p value is greater than 0.02 ; but this does not give information if p value is less than 0.05 for which we reject Ho at 0.05 level or more than 0.05 for whcih we FTR Ho.
hence correct option is A:
A. There is not enough information to make a decision at 0.05

12. Consider a statistical inference that test the null hypothesis be Ho: c against H : esuch that c is a positive value. The test statistic associated with this mull hypothesis is given by t(b-c)/se(b) At significance level a, the test statistic is smaller than the critical value te(a/2, N - 2), that is iste(a/2, N- 2). Mark the correct alternative: (a) The test p-value increases if we increase c. (b) c does not belong to the estimated confidence interval...
(a) Suppose the null and alternative hypothesis of a test are: H0: μ= 9.7 H1: μ >9.7 Then the test is: left-tailed two-tailed right-tailed (b) If you conduct a hypothesis test at the 0.02 significance level and calculate a P-value of 0.07, then what should your decision be? Fail to reject H0 Reject H0 Not enough information is given to make a decision
A test of hypotheses for one proportion has the following Null Hypothesis: pi = 0.33, and uses 0.10 for the level of significance. a. If the calculated value for the associated test statistic equals -1.71, determine the p-VALUE for the test 0.0436 0.4564 0.2262 0.0872 b. If you compare the p-VALUE from Part a to the level of significance, what decision do you make? Fail to Reject Null Reject Alternative Reject Null Fail to Reject Alternative
